Unbreakable Enterprise Kernel
Oracle has released the Unbreakable Enterprise Kernel for x86_64 servers via the Oracle Public Yum Server. Please use the following steps to install the new kernel and any required dependencies.
- Ensure that your system is running Oracle Linux 5 Update 5 (x86_64) before installing the Unbreakable Enterprise Kernel.
- Download and install the Oracle Linux 5 repo file to your system.
# cd /etc/yum.repos.d # wget http://public-yum.oracle.com/public-yum-el5.repo
- Enable both the [el5_u5_base] and the [ol5_u5_base] repositories in the yum configuration file by changing enable=0 to enable=1 in those sections.
- To update your system kernel to the Unbreakable Enterprise Kernel, use the following yum command:
# yum install kernel
- OR To upgrade all recommended packages associated with the Unbreakable Enterprise Kernel, use the following yum command:
yum install oracle-linux
- Reboot your system to run the newly-installed Unbreakable Enterprise Kernel.
Kernel version: x86_64 2.6.32-100.0.19.el5
